Trying to create a global command to launch lighttable (the editor) version 0.8.0

Initially I tried it the i thought easy way and moved the extracted lighttable folder to /opt and then created a symlink

sudo ln -s LightTable /usr/bin/Lt

When that didn't work I changed it to

sudo ln -s ./LightTable /usr/bin/Lt

That didn't work so I have tried to add the directory to my path and then create an alias from there.

The command to execute lighttable is

./Lighttable

so in my ~/.profile I have added

export LT_HOME=/opt/lighttable/ 
export PATH=$PATH:$LT_HOME

then I created my ~/.bash_aliases file and added

alias light="./LightTable"

I then restarted the shell and tried using the alias however it fails

sayth@:~$ light
bash: ./LightTable: No such file or directory

How can I achieve this?

Edit

Couldn't initial locate an answer, have now found

Is there a way to setup ubuntu so that when a new kernel update is installed that it will remove the latest kernel +2? That is not my current kernel not the new kernel but the now useless older kernel. So that I only ever have 2 kernels new and stable.

Can this be set as a default in apt?

Unsure what is interfering with my shell, on every new shell I need to exec $SHELL to get correct settings to take.

I am getting this prompt by default

sayth@sayth-TravelMate-5740G:~$ 

and after exec $SHELL and its working

sayth@sayth-TravelMate-5740G:~$ exec $SHELL
sayth:~$

This question may be a bit basic, but I have read the documentation here https://jujucharms.com/docs/

I understand how I deploy the charms(apps) to a service. But if I want to deploy a django app or php website to my services how do I do this on Juju?

Is there an app in Ubuntu that provides the same integration with Android phones as KDEConnect?

Now that KDE is a framework it mightn't have the same impact of installing libs into my Ubuntu install as it used.to but if there was something designed that would be better.

I followed the instructions here to install Mir on my laptop on Saucy 13.10. Ubuntu Mir

It works well except for a known bug which causes the Laptop to go into low graphics after suspend.

So for a while I would like to go back to default without Mir. Ubsure how I can exactly get this done. What packages do I need to install to get back to default?

How can I install Elixir on Ubuntu 13.04 so that I can easily use it from the command line and update it easily by cloning git.

I have installed Erlang 16 by getting package from here Erlang Downloads

There is a source elixir git here https://github.com/elixir-lang/elixir I can clone it and use it by navigating to the bin directory but how do I set it up so it is available to the system from bash?

I am trying to install Ubuntu. However I have an lvm on the drive I want to install Ubuntu on.

Gparted cannot remove the lvm which is /dev/sda6.

How can I remove the lvm to instal lvm over it?

Is there something Specific I am needing to do to get the unity Gwibber/Social lens to work.

I have gone into system settings and added google account, twitter account and facebook account. When I go to the lens however nothing is displayed at all its blank. I search any term including my name and it states nothing to display. So it remains blank.

If I start gwibber itself it has found and does see my accounts new messages and posts.

Any hints on what to try?

After installing Sabayon, Sabayon took over the boot process. I have reinstalled grub with

sudo grub-install /dev/sda

which I got from ubuntu wiki grub2

Sabayon is an lvm on sda8 and sda9 see below.

However when you update-grub2 it doesn't detect that Sabayon exists, how can I fix this?

Edit I also then tried to redo it using grub-customizer but it just doesn't seem to detect it.

2nd Edit: I think from reading around it doesn't like /dev/sda8 as its a boot partition for the lvm on sda9. It flat out will not recognise it.

How do I create a psuedo command for the terminal?

The basic command for lampp is:

sudo /opt/lampp/lampp start

But I don't want to type this every time so can I create a psuedo for this so I can just type

lampp start
lampp startssl
lampp stop

and so forth so that lampp invokes sudo /opt/lampp/lampp.

Previous I have never used rhythmbox by default because it seemed to be lacking in features to me. Just my personal opinion.

With rhythmbox back in 12.04 will ubuntu give it some attention to give it some usability one thing that was majorly missing on my last use of rhythmbox was an equalizer which is the most basic of requirements for an audio player let alone a preamp.

I have searched and found that on the rhythmbox website the plugin is available but in the plugins menu of rhythmbox it is not there.

I searched google and there are many guides from 2009 trying to install the equalizer. there is nothing recent and one would assume this would be a default plugin, there is no point after all searching for cover art if your music doesn't sound right.

How can I easily install the equalizer in 12.04?

I was having issue with the vim-gnome package and command-t with vim not compiling with the system ruby. So I built vim with.

sudo apt-get install mercurial
hg clone https://vim.googlecode.com/hg/ vim
cd vim
./configure --enable-rubyinterp
make
sudo make install

But I made a mistake. when I did vim --version | grep ruby I realised my error. I had forgotten to turn off rvm before compiling.

   -Wl,-R -Wl,/home/renshaw/.rvm/rubies/ruby-1.9.3-p0/lib -L/home/renshaw/.rvm/rubies/ruby-1.9.3-p0/lib -lruby -lpthread -lrt -ldl -lcrypt -lm  -L/home/renshaw/.rvm/rubies/ruby-1.9.3-p0/lib   

But I can't get apt-get remove it and I cannot see vim in /usr/bin/. It still runs if I type vim, but how do I remove it so I can compile it properly?

renshaw@renshaw-TravelMate-5740G:~/spidermonkey$ 

I was trying to follow from an answer on stackoverflow - install spidermonkey. I am not having much success.

Is that error above resolvable?

I am installing spidermonkey on Ubuntu 11.10. When running ./configure I receive a dependency error that libnotify >= 0.4 is not met.

Located the package in Ubuntu as

gir1.2-notify-0.7

So then I found out where it was installed.

renshaw@renshaw-TravelMate-5740G:~/spidermonkey$ dpkg -L gir1.2-notify-0.7
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/gir1.2-notify-0.7
/usr/share/doc/gir1.2-notify-0.7/copyright
/usr/lib
/usr/lib/girepository-1.0
/usr/lib/girepository-1.0/Notify-0.7.typelib
/usr/share/doc/gir1.2-notify-0.7/AUTHORS
/usr/share/doc/gir1.2-notify-0.7/NEWS.gz
/usr/share/doc/gir1.2-notify-0.7/changelog.Debian.gz

So then I have attempted to add this to PKG_CONFIG_PATH with

export PKG_CONFIG_PATH=/usr/lib/:/usr/lib/girepository-1.0/Notify-0.7.typelib

However I still receive the error.

configure: error: Library requirements (libnotify >= 0.4) not met;

How can I get ./configure to see libnotify as gir1.2-notify-0.7?

I copied a set of BlueJ files from /usr/share/doc/BlueJ to a ~/BlueJ directory however the files in folders are set to root permission and read only I need to be able to read/write them.

So in BlueJ folder there are sub folders for each project for example 'shapes' folder.

I found this command here for changing a singular file File Permissions Ubuntu

user@host:/home/user$ sudo chmod o+x /usr/local/bin/somefile

But how can I change the folder permissions and subsequently all files in folders for every project folder in ~/BlueJ?

I have sound juicer installed and I want to rip to vorbis.ogg. Is gstreamer the best encoder for vorbis or is there a better encoding engine I should use.

The default gstreamer profile is

audio/x-raw-float,rate=44100,channels=2 ! vorbisenc name=enc quality=0.5 ! oggmux

I am going to raise the quality to 0.7 but thats all nothing if gstreamer isn't the best encoder.

Any suggestions for high quality ripping?

Edit: a good answer to this will also be the top search result in google for "best vorbis encoding engine".

Double Edit: It appears oggenc itself is the best encoder which rules out using sound juicer to rip cd's as it uses gstreamer. I have installed oggenc and am testing the command ripper abcde. Found a good configuration for it here oggenc config for abcde

I started by searching guides. I found this guide but neither of the main methods works anymore in 11.10.

1. The first solution, I have created the desktop file, however the file location given as .gconf-> desktop-> unity-> launcher -> favourites no longer exists. I can get to /home/sayth/.gconf/desktop but there is no longer a unity folder.

2. The second solution described right-clicking the desktop and creating a launcher. Right-clicking the desktop no longer produces a "create a launcher" option.

I manually installed geany 0.21 as the one in the repo's is outdated. It's installed and working correctly, and is executing from /usr/local/bin/geany.

How can I add it to the launcher?

There is one small issue with Ubuntu that is driving me crazy. Smooth scrolling when reading documents PDF's isn't smooth. I was using evince to read PDF's and bigger books of 200+ pages. The slightest movement results in a major movement of many pages.

So, I blamed evince and the installed xpdf but no, its the same thing. Is there anything i can install/fix to allow smooth scrolling when I read documents?

In LXDE or KDE, the PDF viewer has the little up and down scroll arrows in the bottom right corner.

Is there anyway to enable these for laptops so we aren't "pulling" at the documents and can scroll PDF's smoothly on laptop's?
